I know this guy and he has this huge transformer that you are supost to plug into the wall then plug all your audio equipment into the transformer.
An externally hosted image should be here but it was not working when we last tested it.

Is this a good power filter for my high end audio project?
How much should i be paying?
Is there any other DIY power filters i can build myself with this thing?
